Doctor Shares 6 Cancer-Fighting Foods To Add to Your Diet Now

What if you could protect yourself from several different types of cancer with foods you already love? We often hear that food is medicine, but some superfoods are better than the rest at staving off serious illnesses such as cancer. So we turned to nutrition expert Joel Fuhrman, MD, author of countless best-selling health books including Super Immunity and Eat for Life, to find out his favorite cancer-fighting foods. Turns out he has an easy way to remember the top picks in his anticancer nutrition protocol. Read along to learn his simple acronym and discover exactly why these foods should be added to your plate.

Can certain foods really reduce your cancer risk?

The science says yes. After poring through the data over the years, Dr. Fuhrman discovered “some foods are more protective than others.” You just have to know which ones to pick. And when you do, the payoff can be huge for your health. In fact, six foods proved more beneficial than the rest. “Hundreds of scientific studies document that these foods prevent cancer and also prolong lifespan in people who have cancer,” he assures.

Meet Dr. Fuhrman’s 6 favorite cancer-fighting foods

Ready to hear the doctor’s go-to grocery list for longevity? In his work as a leading nutritarian, Dr. Fuhrman made up an acronym to help people remember the healthiest plant foods to buy and eat. Simply remember the word: G-BOMBS. That stands for: greens, beans, onions, mushrooms, berries and seeds.

Let’s take a deep dive into this super delicious, healthy list to learn why these foods are the cream of the cancer-fighting crop.

Greens

“The foods with the strongest evidence supporting anticancer and longevity-promoting effects are green vegetables, particularly leafy green cruciferous vegetables,” says Dr. Fuhrman.

The color is key here. These vegetables’ chlorophyll—the same thing that turns leaves green—is known to fuse to cancer-causing chemicals and block them from being digested and absorbed. This natural protective mechanism helps keep harmful compounds from entering your system.

That’s not all. A compound called sulforaphane, found in green cruciferous veggies and microgreens like broccoli sprouts, is considered one of the most protective plant nutrients on the planet by activating the body’s cellular clean-up function.

To get the benefit: Reach for broccoli, cabbage, kale and arugula.

Beans

Fiber-rich beans support a healthy gut microbiome, which is known to boost your immune system in profound ways. But there’s more: When beans are properly fermented in the gut during digestion, they create compounds called short-chain fatty acids such as butyrate, prized for its anticancer effects. In studies, butyrate slows cancer cell growth and flips a switch that essentially tells colon cancer cells to self-destruct, meaning every serving of beans you eat is actively protecting you.

To get the benefit: Dr. Fuhrman recommends beans, peas and lentils. Fermented soy, preferably non-GMO, is also good for women.

Onions

The allium family of vegetables is a superstar. Credit goes to the sulfur and quercetin, powerful compounds that research shows can cause cancer cells to shrink and immunity to soar. Research found that people who ate the most garlic and onions had a 73 percent reduction in ovarian cancer risk and an 88 percent lower risk of esophageal cancer. And garlic is known to help protect against gastric cancer.

To get the benefit: Eat a variety of onions, plus scallions, leeks, shallots and garlic.

Berries

Berries are rich in antioxidants and other flavonoids like resveratrol that are known to dial down inflammation. Research shows that unchecked inflammation in the body is the root of most diseases. “Even dehydrated berry gels and powders have shown positive results in cancer prevention trials in people with both precancerous and cancerous conditions,” Dr. Fuhrman adds.

To get the benefit: Enjoy any berries, plus cherries, citrus and pomegranate.

Mushrooms

These superstars have compounds on their cell walls that can influence immunity and even activate so-called “natural killer” cells—immune cells designed to seek out and destroy sick cells.

Mushrooms are cancer-fighting foods that also inhibit the growth of abnormal cells by blocking their blood supply. Here’s some proof from a PLoS One study: Women who ate 20 grams of healthy mushrooms per day slashed their breast cancer risk by 60 percent.

To get the benefit: Reach for white, cremini, portobello, shiitake and oyster mushroom varieties. Dr. Fuhrman also recommends eating only cooked or dehydrated mushrooms for optimal health and easy digestion.

Seeds

The research on this cancer-fighting food is clear: “Daily consumption of nuts and seeds has been associated with a reduced risk of death from cancer,” reports Dr. Fuhrman.

Why? Plant compounds called lignans are believed to help reduce the risk of hormone-related cancers. Eating as little as two ounces of walnuts a day for just two weeks is shown to help suppress breast cancer, for example. And women with breast cancer who ate more lignan-rich foods (like flaxseeds) had a 71 percent decreased mortality over 10 years, finds research published in the journal Breast Cancer Research and Treatment.

To get the benefit: Reach for walnuts, almonds, flaxseeds and chia seeds.

How to incorporate cancer-fighting foods into your routine

Dr. Fuhrman suggests eating a wide variety of G-BOMBS foods daily, adding some to each meal. “You are the cure,” he reminds.

He makes this call to action to protect your life: “Every day when we sit down to eat, we have a choice. We can either eat foods that help our bodies and minds, or we can eat foods that harm us and increase dangerous health risk factors.”

Bottom line: We know cancer is scary. But there is empowering news and hardworking experts trying to spread the information that can save lives. We really have a lot of control over what we eat. “Our bodies are powerfully resistant to disease when provided with an optimal diet and micronutrient excellence!” Dr. Fuhrman encourages.
